SteemJs注册的两种方法 / 网络研习社#56

参考steemsnippets |　创建免费用户 |　Claiming a discounted (“free”) account |　创建用户

这两天在社区中查找了SteemJs用户注册的实现方法，还好，测试了下，也都实现了！Steem在原有的基础上提供了一种新的免费注册的方法（discounted_account），这种新方法可以比较快速地完成新用户注册。

SteemJs注册主要有两种方法：一是create_discounted_account，另一个是accountCreate。create_discounted_account是用消耗RC注册，一个新号需要约10,445,334,023,565 RC，SP大户才能玩得转。像我的帐户（lemooljiang）一天也只能注册２～３个。accountCreate就是付费注册(3个steem)，其它的就没什么限制了。

create_discounted_account

如上图所示。

这个是用dsteem来完成注册功能，有两步，一步是申明帐户(claim_account)，使其处于Pending状态；第二步是就是直接注册了(create_discounted_account)。

  1. 安装和挂载

    cnpm install dsteem --save
    //main.js
    const dsteem = require('dsteem')
    const client = new dsteem.Client('https://api.steemit.com')
    Vue.prototype.dsteem = dsteem
    Vue.prototype.client = client

  2. 两个注册函数

    claim_account() {
      const creator = "lemooljiang"　　//创建帐户的用户名
      const active_key = "5Jffffffffff"　//创建帐户的资金密钥
      return new Promise(resolve => {
          const wif = this.dsteem.PrivateKey.fromString(active_key)
          const fee = this.dsteem.Asset.from(0, 'STEEM')
          const op = [

              {
                  creator: creator,
                  extensions: [],
                  fee: fee
              }]

          this.client.broadcast.sendOperations([op], wif).then(function (result) {
              console.log('11,Included in block: ' + result.block_num)
              console.log('222，申明新帐户创建成功！' )
              resolve("ok")
          }, function (error) {
            console.error(error)
            console.log('333，申明新帐户创建失败！' )
            resolve("err")
          })
      })
    },
    create_discounted_account() {
      const creator = "lemooljiang"　　//创建帐户的用户名
      const active_key = "5Jofffffffffffff"　//创建帐户的资金密钥
      const username = this.username　　//新帐户名
      const password = this.password　　//新帐户的密码
      return new Promise(resolve => {
          const wif = this.dsteem.PrivateKey.fromString(active_key)
          const prefix = this.client.addressPrefix
          const ownerKey = this.dsteem.PrivateKey.fromLogin(username, password, 'owner').createPublic(prefix)
          let owner = this.dsteem.Authority.from(ownerKey)
          const activeKey = this.dsteem.PrivateKey.fromLogin(username, password, 'active').createPublic(prefix)
          let active = this.dsteem.Authority.from(activeKey)
          const postingKey = this.dsteem.PrivateKey.fromLogin(username, password, 'posting').createPublic(prefix)
          let posting = this.dsteem.Authority.from(postingKey)
          let memo_key = this.dsteem.PrivateKey.fromLogin(username, password, 'memo').createPublic(prefix)

          const metadata =  {date: new Date()}
          const create_op = [
              'create_claimed_account',
              {
                  active,
                  creator,
                  extensions: [],
                  json_metadata: metadata ? JSON.stringify(metadata) : '',
                  memo_key,
                  new_account_name: username,
                  owner,
                  posting,
              }
          ]

          this.client.broadcast.sendOperations([create_op], wif).then(function (result) {
              console.log('22, Included in block: ' + result.block_num)
              console.log('666，新帐户创建成功！' )
              resolve("ok")
          }, function (error) {
              console.log('444，新帐户创建失败！' )
              console.error(error)
              resolve("err")
          })
      })
    },

accountCreate

这种方法简单直接，付点小费创建就可以啦。

它主要由steem的两个方法来实现：steem.auth.generateKeys 用于生成4组密钥(owner, active, posting, memo)，steem.broadcast.accountCreate 用于创建账号。
